READY OPENING AND SELF SEALING CARTON Filed Nov. 14, 1928 Patented Apr.29, 1930 UNITED STATES PATENT OFFICE ALBERT J. GANZ, OF LOS ANGELES,CALIFORNIA READY-OPENING AND SELF-SEALING- CARTON Application filedNovember 14, 1928. Serial No. 319,407.

One of the important objects of this invention, is the provision, in acarton, particularly for cereal products and the like, of means foreconomically and quickly removing any portion of the contents withoutdisturbing or marring the appearance of the package and,

which further provides means for automatically closing and again sealingthe package after the desired quantity of its contents have beenremoved.

Still another and further important object of this invention, is toprovide a cardboard carton or package, which, while possessed of theready-opening and self-sealing features, will at the same time beeconomically constructed and capable of ready manufacture inconsiderable quantities with a minimum expenditure of material andlabor. Other and further important objects of this invention will beapparent from the disclosures in the accompanying drawings and followingspecification. I

'The invention, in a preferred form, is illustrated in the drawings andhereinafter more fully described.

In the drawings:

Figure 1 is a perspective view of the improved self-sealing cartonof-this invention, showing the same in operation.

Figure 2 1s a side view of the same.

40 Figure 3 is a view similar to Figure 2, illustrating a slightmodification. 1

Figure 4 shows still another modification as shown in the drawings:

The reference numeral 10 indicates generally the improved carton of thisinvention,

one face or side of which is provided with certain heavily scored,perforated, or partly cut lines, preferably of the configuration shownat 14, in Figure 2, the two lines 14, ap-

- proaching each other upwardly at an angle of substantially 120, butnot quite meeting at their apex, at which location there is provided adownwardly curved heavily scored, perforated, or partly out line asshown at 16. These scores, perforations, or cuts are formed in thecarton to such a depth and in such a manner that the package may bereadily opened along these lines by comparatively light pressure of thefingers or the like.

Associated with these heavily scored or partly cut lines 14 and 16, is anumber of other scored lines, which, however, are not so deeply made andwhich are illustrated at 18, 20 and 22 in Figure 2, being shown inlighter unbroken lines so as to distinguish from the more heavily scoredor partly cut lines 14 and 16.

The scores may be replaced as stated by lines cut entirely through thematerial, the parts being'held in place by certain uncut spaces, thisbeing known as a nicked or perforated cut. The scores 20 and 22 are.also designated as heavy cut scores while the scores 18 are merelycrease scores.

The crease score line 18, extends directly across the package, and isparallel to the top and bottom edges, while the scores 20 join the endsof the line 18 at their outer ends and are themselves formed parallel tothe deeper scores Hand 16, having, however, a common meeting point atthe middle of the sides of the carton. At this point begins the scoredline 22, extending upwardly and longitudinally along the middle of theface 12, and this scored line 22 joins the lowest central portion of thedeeply scored curve 16.

It will be obvious that after the heavily scored, perforated, or partlycut lines 14 and 16 are punched out and an opening is made, a

and more easily controlled stream of small grained materials, such assalt, sugar or the like, while in packages used for cereals and largerand lighter grained goods, this depression is not so necessary.

It Will be obvious that other forms and adaptations of this device maybe used, as, for example; by providing a heavy scored, perforated, orpartly cut curved line as shown at 26 in Figure 4, this beingpreferably, parallel to a lighter scored line 28, the two having theirmiddles joined by a longitudinal still more lightly scored line 30. Thisconstruction is also preferably provided with the transverse crease line18.

It will be evident that herein is provided a package which isparticularly adaptable for food stuffs and any other or similarperishable products; and which combines in a simple construction, meansfor adequately protecting the contents, While at the same time 'animmediate, ready and convenient access is provided to the goodsthemselves.

I am aware that many changes may be made and numerous details ofconstruction varied throughout a wide range without de-- parting fromthe spirit of this invention, and I therefore do not purpose limitingthe patent granted hereon, otherwise than as necessi- V tated by theprior art.

I claim as my invention:

1. A ready-opening and self-sealing carton,

including in combination, a top, sides, and

'bottom; one of the sides provided with a plurality of heavily scoredlines adapted to be converted into self-closing cuts for use, and anumber of lightly scored lines adapted to provide bends but not cuts,said heavily scored lines being at angles to the side edges of thecarton and converging adjacent to the middle of said side, and one ofthe lightly scored lines parallel to the side edges of the carton andjoining the said heavily scored lines.

2. A ready opening and self-sealing ca rton, including in combination, atop, sides and bottom; one of the sides provided with a tiveness of saidopening, without actually penetrating the material of the carton.

4. A ready opening and self-sealing carton, including in combination, atop, sides and bottom; one of the sides provided with a plurality ofheavily scored lines adapted to be converted into self-closing cuts foruse, said heavily scored lines comprising nicked perforations and beingat angles to the side edges of the carton and converging adjacent to themiddle of the side,-and certain other lines more lightly scored, andparallel respectively to the side and bottom edges of the carton,together with a downwardly curved scored line joining the lightly scoredstraight lines.

In testimony whereof I afiix my signature.

ALBERT J. GANZ.

plurality of cuts, said cuts being atangles to the side edges of thecarton and converging adjacent to the middle of the side, and aplurality of scored lines in addition to the cuts, all adapted toprovide an opening in the side of the carton upon the application ofpressure to the face thereof.

3. A ready opening and self sealing car-
